PENNSYLVANIA, A CORPORATION OF MACHINE FOR FINISHING FLOORING.

Application filed m a1, 1919, Serial'N'o. 314,465.

certain new and useful Improvements in' Machines for Finishing Flooring, of-which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to a mach ne for finishing flooring, and is a companlon application of my application Serial No. 314,464 filed July 31, 1919, the ob ect of the present invention being to provide means for applying a coat of varnish to the strlp of flooring which has been filled by the above mentioned machine and allowed to dry.

. Another object of my invention is to provide a construction of apparatus which is substantially the same as shown in my companion application, with the exceptionthat the parts are re-arranged and additional parts'are added in order to carry out the method of varnishing a strip of flooring so as to apply a smooth surface.

Al still further object of the invention is to provide a novel form of polishing device for polishing the surface before the coating of varnish is applied.

Other and further objects and advantages of the invention will be hereinafter set forth and the novel features thereof defined by the appended claims.

In the drawings:

Figure 1 is a side elevation of an apparatus constructed in accordance w1th my 1nvention.

Figure 2 is a top plan view of the delivery end of the apparatus shown in Fig. 1.

Figure 2 is a top plan view of the feed end of the apparatus.

In the drawing 1 indicates a frame provided with driving mechanism constructed substantially as shown in my companion application, Serial No. 314,464, and provided with a guideway 2 constructed identically as shown in the above referred to application. The guideway is adaptedto receive a strip of flooring 3 which has been previously coated with a filling com osition and is moved continuously throu the guideway by feed rollers 4 and 5 hel in contact with the opposite faces f the strip by mecha- Benewed November 11, 1922. Serial No. 600,477.

nism constructed identicall as shown in the machine for filling the strip, which mechanism consists broadl in arms 6 and 7 connected to a crank carried by a rock shaft by links, said rock shaft having a weighted arm 8 connected thereto to which is connected a lever 9, by means of which the weighted arm can be raised so as.to move the feed rollers 4 and 5 out ofcontact with the strip. The feed rollers 4 and 5 are revolved through the medium of gears 10 which mesh with gears 11 carried by shafts 12, one of said shafts being provided with a bevel gear 13 meshing with pinion 14 carried by a shaft provided with a pulley over which passes a drive belt from a driven shaft 15, the above construction being described broadly so that the operation will be clearly understood.

Arranged to one side of the guideway 2 is a plurality of rollers 16 which are adapted to engage one face of the strip'of flooring so as to hold the same against lateral pressure. Arranged opposite the rollers16 is a circular polisher 17 which comprises a disk'having .a coiled fabric 18 secured to the face thereof which is adapted to engage the face of the strip of flooring so as to polish the surface before the coat of varnish is applied. The polisher 17 is carried by a shaft supported by a carriage 19 mounted on a suitable guideway 20 which is adjusted therein by a hand wheel 21 whereby-the o1- isher can be adjusted in respect to the ace of the flooring strip so as to' apply the proper pressure as the same is revolved. The shaft of the polisher carries a pulley 22 over which passes a belt 23 extending from a pulley carried by the driven shaft 15, the construction of driving means and support for the polisher being substantially the same as that shown in my companion case used for supporting the circular wiper.

The upper bearing for one of the shafts 12 carries a split collar 24 having an extension to which is connected an arm 25 provided with a bearing 26 in which is mounted a shaft 27 carrying a brush 28 for removing the dust formed by the polisher so that the strip of material will be thoroughly cleaned before it reaches the varnishing device. The shaft 27 carries a pulley over which extends belt 29 which is driven by apulley'carried by one of the shaft 12 this construction being substantially the same as that shown in my companion application.

\ which the strip of flooring is adapted to pass so that the previously filled surface will be given a coat of varnish, the movable guideuays and pressure bars contacting with the surfaces of the strip so as to prevent the escape of varnish from the receptacle around the discharge opening thereof.

As the stri of flooring moves past the varnish applying receptacle it 15 brought into contact. with a series of brushes 31 which are supported by portions 32 secured to the guide members of the guidcway, so as to give an even flow to the varnish oi; sprea the varnish evenly upon the surface of the stri I iom the foregoing description it will be seen that I have provided an apparatus for finishing flooring, having means for applying the first coat of varnish to the previously filled surface, by means of which I am able to use a construction of apparatus substantially the same as that shown in my above application designated Serial No. 314,- 464 with r the exception that the polisher is arranged in advance of the liquid applying receptacle, and the series of brushes are arranged to apply the varnish for spreading and forming'a smooth surface.

In the operation of the apparatus as herein shown for applying the first coat of varnish to a strip of flooring which has been previously filled, the strip of flooring which has been passed through a filler machine is forced into the guideway and the feed rollers force the strip to move continuously in their passage through the machine, and the partly finished surface of the strips is polished, then cleaned, and then coated with varnish, which varnish is spread evenly over the surface by a series of stationary brushes so that when the strip is discharged from the machine it will be given an even coating of varnish.

In the drawings I have shown an apparatus for applying and finishing only one face of a strip of lumber in its passage through the machine, but it is of course understood that the members for. applying the coating of varnish and finishing the same could be duplicated so that both facw of the strip would be finished in its passage through the machine, and .while I have described the operation of the apparatus in coating and finishing a strip of flooring, I do not wish to limit myself to the finishing of any particular kind or form of strip, as wainscoting or molding could be varnished been filled, consisting of means for moving a strip of flooring continuously in a guideway for supporting the same on edge, means for polishing the face of the strip in its passage through said guideway, means for causing said strip in its passage through said guideway to move over the discharge opening of the varnish containing receptacle, and a series of brushes arranged in the path of travel of said strip for spreading the varnish applied by the receptacle.

2. An apparatus for varnishing a strip of lumber comprising a guideway for supporting and guiding a strip of lumber on edge in its passage therethrough, means for moving the strip continuously, a revolving polisher arranged in the path of travel of said strip for polishing one face thereof, a revolving brush for cleaning the strip, a receptacle having a discharge opening over which said strip passes for applying a coating of varnish thereto, and a series of stationary brushes arranged in the path of travel of said strip."
